NOTE: The bowl should always be drained before water or
contaminant levels reach the bottom of the depressurizer cone. Check daily with the engine off. Always open the draincock or remove the pipe plug completely to flush particulates out. Failure to do so could cause a leaky valve.
A. DAHL Units Mounted HIGHER Than Fuel Storage Tank 1. Turn engine off. Vent the DAHL filter to allow draining.2. Loosen the outlet fitting compression nut (see Illustration 4 on Page 2) and then open the draincock or remove the pipe plug. If your fuel system is equipped with a DAHL primer bulb, open the draincock and squeeze the primer bulb to evacuate all contaminants.

SERVICING
3. Close the draincock or replace the pipe plug and follow the priming instructions shown below.
B. DAHL Units Mounted LOWER Than Fuel Storage Tank 1. Turn engine off and close shut-off valve. (Valved Manifold units may be drained and elements replaced with the engine running at idle. Close the inlet and outlet valves to isolate the filter being serviced.)
2. Open the draincock or remove the pipe plug completely and drain all contaminants.
3. Close the draincock or replace the pipe plug and follow the priming instructions shown below.
A. When To Replace
As a general guideline, depending on fuel quality and engine use, elements should be replaced as follows:
1. DAHL 101 is a 2 micron element which can be used approximately 500 hours or 20,000 miles. (DAHL 101-W is a 10 micron element for use in winter or severe applications and DAHL 101-30 is a 30 micron element.)
2. If you have a vacuum gauge, the first replacement should be made at the very first indication of power loss at high RPMs. Make a note of the vacuum gauge reading at this point. The differences in various fuel system requirements make it impossible to predict what this reading will be. Mark the reading on the gauge dial or the unit for future element replacement.
B. How To Replace Contaminated Element
1. Open the draincock or remove the pipe plug completely to empty the bowl and flush particulates out. Failure to do so could cause a leaky valve.
2. Loosen, but don’t remove, the lid clamp knob. Support the filter body with your hand prior to release.
3. Remove the element with a turning motion. At this point, you may clean the outside of the filter body. Use only clean diesel fuel or kerosene and wipe clean.
4. Check the centerpipe O-Ring and replace if hard or damaged.
5. Remove and replace the lid gasket. Be sure the lid groove and body lip are clean. (Grease the lid cover gasket before positioning.)
e leMent r eplACeMent ______________________________________________
C. Reassembly
1. Lubricate the top and bottom element gaskets. Install the element onto the centerpipe with a turning motion.
2. Fill the filter body with clean diesel fuel to within one inch of the top.
3. Double check the lid cover gasket position in the lid groove.
4. Attach the body to the lid and hand tighten the lid clamp knob. Check the circumference of the body and lid for proper clamp alignment. (See “up” arrows on band for correct orientation.)D. Priming
1. Eliminate air
—
use existing fuel system primer, if so equipped.
a. If the DAHL primer bulb is installed, loosen the swivel fitting on the outlet port and squeeze the bulb repeatedly until the diesel fuel appears at the swivel. Then tighten the swivel fitting.
B. If no primer bulb is installed, remove the inlet port elbow fitting and fill to the top with clean diesel fuel. (Or, if you can pivot the unit upside down, prime it through the bowl plug.)
For ease of priming, installation of a primer pump kit (140-50 KIT) with every Model 100 series is recommended.
2. Start engine and check for leaks.
NOTE: For any marine or other unit utilizing the heat deflector shield,
clean the shield to remove any accumulated diesel fuel.
Engine starting and power loss problems from the fuel system are usually caused by one or more of the following:A. Air Leaks
1. Fittings. Insure the O-Rings on the fittings in the DAHL filter ports are lubricated and not damaged, cracked or dirty.NOTE: When using JIC 37° fittings, be sure only mating JIC
37° fittings are used. Misalignment will occur and air leakage will result from an attempt to fasten a 45° fitting to a JIC 37° fitting. Check for fitting looseness, seat dents, misalignment or unmatched threads. All fittings must be wrench tight.
2. Bubbles In The Bowl. If bubbles appear at the depressurizer cone, a leak is indicated between the fuel tank and the inlet port.
NOTE: Old fuel lines (rubber hose or metal tubing) may crack
when moved. Check areas around push-on fittings, pipe adapters, hose clamps, etc. If air bubbles appear at the draincock, check for particles stuck in the valve seat or a partly open draincock. Also check for defective, miscentered or unlubricated bowl gaskets. Check the bowl plug O-Ring to make sure it is not cracked or extruded out of place. The bowl plug should be hand tightened only.
3. Gaskets. If the lid or bowl has been removed, make sure the gasket grooves are clean. Inspect the gaskets for proper seating in the grooves. Lubricate the gasket(s) with oil or grease.B. Clogging And Restriction
1. Fuel Lines. Check for collapsed lines caused by sharp bends or excessive turns. Check the tank and/or filter shut-off valve(s).
2. Filter Elements. Early clogging can occur from badly contaminated fuel (micro-organism growth, rust, sludge, dirt, etc.) Always carry a spare DAHL element. Asphaltinic materials (fuel oxidation products), which are normally harmless to the injection system, can eventually plug original equipment filters remaining in the fuel system. If problems persist after the DAHL element has been replaced, also replace the other fuel filter elements.
3. Filter Inlet. Severely contaminated fuel may cause inlet plugging. In this event, close the fuel tank supply shut-off valve (if equipped) and disconnect the inlet line. Remove the bowl and clean the inlet. Should the depressurizer cone also be plugged, disassemble and clean out.
4. Bleed Back. If fuel in the DAHL filter bleeds back to the fuel tank, an air leak or reverse flow valve problem is indicated. Inspect fuel lines and fittings first as indicated above. If the reverse flow valve is clogged, use air or clean fuel to flush out.C. Malfunction Of Engine Parts
Pre-existing conditions in pumps and injectors can also cause power loss and engine starting problems. See your equipment dealer if the above troubleshooting guides do not cover your problem.
TROUBLESHOOTING
4
1. The contaminated fuel enters the inlet port.
2.
The T-Bolt redirects the fuel downward through the centerpipe.
3. Fuel flows through the reverse flow valve.
4. Fuel flow is spread by the depressurizer cone.
5. As fuel is discharged from the depressurizer cone, 80% of contaminant separation takes place. Most of the solid particles and water settle into the quiet zone of the bowl.
6.
As the fuel rises upward, any remaining minute water droplets coalesce on the cone, baffle and bowl surfaces. Droplet size and weight gradually increase, causing downward flow into the sump.
7.
Fuel is filtered completely by the element, which contains HydroShield ™ media. The clean fuel then continues upward through the outlet port and on to the pump and injection system.
HOW THE DAHL SYSTEM WORKS
REBUILD PROCEDURE
If it is ever necessary to dismantle the unit for inspection and/or possible repairs, refer to the parts illustration. Then follow these simple steps:
1. Refer to the appropriate ELEMENT REPLACEMENT steps for disassembly. (Dismount if desired.)
2. Remove the socket head bolts from the bowl ring to release the bowl. Stubborn bolts are easily removed by “shocking” the head. Place the allen wrench into the bolt and lightly rap the wrench with a hammer. Remove the bolt.
3. Unscrew the depressurizer cone to inspect the reverse flow valve. Caution: Cone edges are sharp. Use gloves or a rag for protection.
4. Check all parts for damage. Replace all damaged parts or hard gaskets. (Order 100-GK — Gaskets for 100 Series.)
5. Refer to the parts illustration for reassembly. Clean all gasket grooves and contact surfaces of foreign matter. Coat the lid cover gasket with grease and all other gaskets and O-Rings with diesel fuel. Hand tighten the depressurizer cone and wrench tighten the socket head bolts.
6. Again, refer to ELEMENT REPLACEMENT section to finish reassembly.
